On May 4, Pfizer announced the suspension of patient recruitment for the Phase 2 clinical trial MagnetisMM-3 of its BCMA/CD3 bispecific antibody elranatamab, due to 3 cases of peripheral nerve damage in the clinical trial
.
Previously, the Phase 1 clinical trial of the drug showed that the response rate was as high as 83%.
In early February of this year, Amgen announced the temporary termination of clinical studies of three bispecific antibody projects, including the BCMAXCD3 target bi-antibody drug AMG 701 (pavurutamab)
.
The main reason for the termination of AMG 701 was safety factors.
I used to think that in the peak competition of ADC, CAR-T and bispecific antibody on the BCMA target, BsAb would have the last laugh, but the result would be defeated again and again
.
Theoretically speaking, if CAR-T can succeed, BsAb has a great probability of success.
